When it comes to the head supports on our high-back boosters, you want to go ahead and lower that head support. So the shoulder belt guide is about 1/2 an inch to an inch above the child's shoulders. You'll have to find that range that gives the best shoulder belt fit, but that's a good place to start. You don't want it higher and you don't want it lower, you want that shoulder belt so it's resting right on the collarbone and not hovering above the collarbone, and not going over the shoulder. We want it to lay flat across the collarbone.

Remember, on a booster head support you want that shoulder belt guide half an inch to an inch above the child's shoulders.

When you want to start thinking about moving your child to a Booster Seat from their forward-facing convertible seat with a 5-point harness, there's a couple things you want to consider. First, their height and weight. If they've exceeded either one of those capacities for their forward-facing seat, then it's time to consider putting them in a Booster Seat. The other thing that you want to think about is their maturity level typically.

Around age 5 is when most kids are mature enough to sit in a booster seat. And the reason maturity is important is because you want that child to sit still in a Booster Seat, and not moving around and moving out of position so that the seat belt isn't fitting them correctly. So if your child can do that for the entire ride in a Booster Seat, then they're mature enough to sit in a booster.

Consult the instruction manual that comes with the car seat. It will state whether a seat can be used with Ford's inflatable seat belts.

Because we can no longer test convertible and booster seats with Ford’s inflatable seat belts, new seats going forward will not allow them to be used and this will be stated in the instruction manual that comes with the seat.

Diono all-in-one seats manufactured in 2017 and prior, and the Cambria and Monterey booster seats manufactured in 2017 and prior will continue to be approved for use with Ford's inflatable seat belts.
